Micropump

A pump comprising:

• a disposable component comprising:
• a disposable component inlet port coupled to a first disposable conduit in fluid communication with a fluid medium source, wherein the first disposable conduit comprises a disposable piston pump assembly and a disposable bubble eliminator, and the first disposable conduit is in fluid communication with a disposable component outlet port, wherein the disposable bubble eliminator is in fluid communication with a lumen of the first disposable conduit and is operable to reduce a gas content of a fluid medium;
• wherein the disposable piston pump assembly comprises a plunger in direct contact with the fluid medium, and wherein the disposable piston pump assembly is operable to pump the fluid medium from the disposable component inlet port, through the first disposable conduit and the disposable bubble eliminator, to the disposable component outlet port;
• a first one-way outlet valve disposed in the first disposable conduit between the piston assembly and the disposable bubble eliminator and operable to prevent the fluid medium from flowing from the disposable bubble eliminator to the disposable piston pump assembly;
• a second disposable conduit that places the disposable bubble eliminator in fluid communication with a disposable flow meter;
• a second one-way outlet valve disposed in the second disposable conduit between the disposable bubble eliminator and the disposable flow meter and operable to prevent the fluid medium from flowing from the disposable flow meter to the disposable bubble eliminator;
• and
• a reusable component comprising:
• a reusable movable stage operable to compress the disposable piston pump assembly;
• a reusable mechanical actuator operable to drive the movable stage;
• a reusable reception tunnel configured to receive at least a portion of the first disposable conduit;
• a reusable inlet valve operable to close the first disposable conduit when the at least a portion of the first disposable conduit is disposed in the reusable reception tunnel;
• a reusable flow meter connector operable to connect to the disposable flow meter and to convey data from the disposable flow meter;
• and
• a reusable bubble detector.
